Manipulating the shape of flexible magnetoelastic nanodiscs with meron-like magnetic states
Beatriz Miranda-Silva, Pedro H. C. Taveira, Allison W. Teixeira +4
The control of the magnetic properties of shapeable devices and the manipulation of flexible structures by external magnetic fields is a keystone of future magnetoelectronics-based…
Orbit-like trajectory of the vortex core in a magnetic nanodot
D. A. Carvajal, A. Riveros, J. Escrig
In physics, conserved quantities are key to understanding and describing physical phenomena. These conserved quantities are related to Noether's theorem and the Lagrangian descript…
General method to perform Microcanonical Monte Carlo Simulations
G. Palma, A. Riveros
Monte Carlo simulations have boosted the numerical study of several different physical systems and in particular, the canonical ensemble has been especially useful because of the e…
Controlling the nucleation and annihilation of skyrmions with magnetostatic interactions
N. Vidal-Silva, A. Riveros, F. Tejo +2
Skyrmions have become one of the most visited topics during the last decade in condensed matter physics. In this work, and by means of analytical calculations and micromagnetic sim…
Surface anisotropy in a magnetic cylinder induced by the displacement of a vortex core
A. Riveros, D. A. Carvajal, J. Escrig
In this article we investigate the induction of a surface anisotropy due to the displacement of the vortex core in a cylindrical nanostructure. In fact, the effect of the displacem…
Distinct magnetic field dependence of Néel skyrmion sizes in ultrathin nanodots
F. Tejo, A. Riveros, J. Escrig +2
We investigate the dependence of the Néel skyrmion size and stability on perpendicular magnetic field in ultrathin circular magnetic dots with out-of-plane anisotropy and interfaci…
Analytical and numerical phase diagrams for cobalt nanostructures: stability region for a Bloch skyrmion
A. Riveros, N. Vidal-Silva, F. Tejo +1
In this letter we calculate the energies corresponding to the different magnetic phases present in a ferromagnetic cylinder by means of analytical calculations. From the comparison…
Stability of Neel skyrmions in ultra-thin nanodots considering Dzyaloshinskii-Moriya and dipolar interactions
N Vidal-Silva, A Riveros, J Escrig
An analytical expression for the energy of Néel skyrmions in ultra-thin nanodots considering exchange, uniaxial anisotropy, Dzyaloshinskii-Moriya, and dipolar contributions has bee…
Finite-size corrections to scaling of the magnetization distribution in the -model at zero temperature
G. Palma, F. Niedermayer, Z. Rácz +2
The zero-temperature, classical -model on an square-lattice is studied by exploring the distribution of its centered and normalized magnetization in t…
Analogies between nuclear physics and Dark Matter
Dante Carcamo, Alejandro Riveros, Jorge Gamboa
A fermionic description of dark matter using analogies with nuclear physics is developed. At tree level, scalar and vector processes are considered and the two-body potential are e…
Meron-cluster simulation of the quantum antiferromagnetic Heisenberg model in a magnetic field in one- and two-dimensions
G. Palma, A. Riveros
Motivated by the numerical simulation of systems which display quantum phase transitions, we present a novel application of the meron-cluster algorithm to simulate the quantum anti…
